The staircase design, Karst, is named from the Karst terrain, which is famous for solutional caves.
Its cave form can allow people to see and hear the flowing water, and the function can create the process that acid rain acts with the bags of crushed oyster shell to reduce ocean acidification by absorbing carbon dioxide. The water containing dissolved bicarbonates can contribute an alkaline (High pH) source as an antacid to help neutralize acidified ocean.
Also, its modular water-filtering system can bring the sensation of nature into the house, connecting the community of humans and water.
